The seeds were preheated by dry and wet methods at three temperatures (50, 70 and 90 degrees C) for 10, 20, 30 and 60 minutes. The oil was extracted using the Soxhlet method with hexane. The results showed a significant change in oil acid value when heated at 90 degrees C for 60 minutes, with values of 2.76+or-0.18 for the dry method and 2.90+or-0.14 for the wet method. Heating at the same conditions yielded peroxide values of 10.70+or-0.03 for the dry method and 11.95+or-0.08 for the wet method. Author A. L. Khandare, U. Kumar P, R. G. Shanker, K. Venkaiah and N.

This study focused on the antimicrobial potential of the fruit of Crescentia cujete or Calabash tree against common infections Staphylococcus aureus, a gram-positive bacteria, and Escherichia coli which is a gram- negative bacterium. Fruit extracts were obtained by maceration with ethanol for 24 hours at room temperature. The experimental research design was used through disc diffusion method. Findings of this study, however, revealed no antibacterial effect of the fruit extract against Staphylococcus aureus and Escherichia coli. Keywords: Crescentia cujete, antimicrobial, Staphylococcus aureus, Escherichia coli INTRODUCTION The healing power of plants is a widely explored study. Plants have been traditionally used for the treatment of infection of different aetiology. More so now with the development of bacterial resistance of some microorganisms due mainly to the abuse of antibiotic use. The increasing prevalence of multidrug-resistant strains of bacteria and the recent appearance of strains with reduced susceptibility to antibiotic raises the spectre of untreatable bacterial infections and adds urgency to the search for new infection-fighting strategies (Sieradzki, Roberts, Haber & Tomasz, 1999) as 80 International Peer Reviewed Journal cited by Mahbub et al.

ABSTRACT Green synthesis is one of the rapid, reliable, and best methods for the synthesis of silver nanoparticles at ambient temperature without application of hazardous agents. The present study described the formation of silver nanoparticles by the flower extracts of Tabebuia argentea. Synthesized silver nanoparticles were characterized by UV-vis spectroscopy, Scaning electron microscopy and X-Ray diffraction studies. Silver nanoparticles synthesized have shown significant antibacterial effect and the outcome of our study propose that the produced silver nanoparticles bestow superior substitutes in drug development.

Nanoparticles are more active and exhibit unexpected properties because of high surface to volume ratio and quantum size effect. Nanoparticles (NP’s) of metals like Ag and Cu are found to exhibit enhanced optical and catalytic activity due to the quantum size effect. They have distinct physical, chemical, electronic, electrical, mechanical, magnetic, thermal, dielectric, optical and biological properties [1]. Metal NP’s are considered as building blocks for the next generation optoelectronics [2], electronics [3], and various chemical and biochemical sensors [4] as they have advantages over bulk materials.

This study primarily aimed to present preliminary characterization of the fruit extracts and fruit pulp of Crescentia cujete L. using several analytical techniques. Characterization of the crude MeOH extract and pure compound, trans-cinnamic acid, isolated from the fruit extract were performed using gas chromatography-electron ionization-mass spectrometry (GC-EI-MS). Lyophilized pulp was characterized by energy dispersive X-ray spectroscopy (EDX). Hydrochar samples resulting from hydrothermal carbonization (HTC) of fruit pulp were characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Eight constituents were eluted from the crude MeOH extract which were mainly composed of furan (5-Hydroxymethylfurfural, 53.99%), a pyranone derivative (2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4- one, 8.68%) and a carboxylic acid (3-phenyl-2-propenoic acid, 7.94% or compound 5). Other notable compounds of the extract include furaneol (0.78% and 1.56%), phenol, 2,4-bis(1,1-dimethylethyl)- (3.73%), benzenepropanoic acid, 3,5-bis(1,1- dimethylethyl)-4-hydroxy-, methyl ester (1.15%) and n-hexadecanoic acid (0.59%).

While the C. odollam plant has multiple practical and ornamental functions, its seeds have traditionally been utilized for suicidal and homicidal purposes in many parts of the world. Physicians should be aware of the presentation, diagnosis, and treatment of C. odollam ingestion given the current ease of availability of these seeds in the United States and the increased reports of suicide attempts. 1.

Phytochemical constituents were investigated both qualitatively and quantitatively. Methods: The leaf extracts of Cerbera odollam Gaertn were prepared by drying and extracted using Soxhlet apparatus into methanol and aqueous media, which were subjected to phyto- chemical screening. Total phenols, tannins, flavanols, alkaloids and its antioxidant activity were determined using spectroscopic techniques. Antimicrobial activity were determined using well diffusion method. Results: Aqueous extract exhibits higher content of phenols, tannins, flavanols and alkaloids, whereas methanol extract exhibits higher content of anthocyanin and cardiac glycoside respectively. Aqueous extract exhibits higher inhibitory concentration (IC %) value for DPPH (2, 2-Diphenyl-1-picrylhydrazyl) and H2O2 radical scavenging assay and reduc- ing power (RP) assay. The methanol extracts exhibited higher inhibitory concentration (IC %) value in SO and NO radical scavenging assay, exhibiting antioxidant properties in five antioxi- dant models that were investigated. The methanol extract showed some antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Salmonella typhi and Escherichia coli with inhibitory zone ranging from 2 mm to 3 mm, whereas the aqueous extract showed no activity. Abinash Sahoo, High antifungal activity was found against Saccharomyces cerevisiae and Candida albicans for methanol extract and moderate for aqueous extract with inhibitory zone ranging from 9mm Thankamani Marar* to 26 mm.

    LANDMARK TREES City of Fremont L A N D M A R K T R E E S OF THE C ITY OF F REMONT Printed: August 2012 Landscape Architecture Division Community Services Department L A N D M A R K T R E E S introduction Drawings: Phillip Eaker In May of 1966, the City of Fremont, sponsored by the City Beautiful Committee, adopted a tree preservation ordinance to encourage and promote the preservation of trees. In August of 1970, the City Beautiful Committee received approval by the city council to conduct a survey of specimen trees for the final selection of outstanding landmark trees. The survey indicated the findings of 124 landmark trees to be preserved under resolution no. 3027, adopted in May 16, 1972. Several locations of the original 124 trees were inaccessible or hidden from public view. As a result, the list was reduced to sixty.1 The first publication containing the sixty landmark trees was published in 1973. The pages were black and white and each tree had beautifully hand-drawn sketches for visual reference. Since then, the publication has been a living encyclopedia of Fremont’s natural heritage. New trees were given landmark status by City Council over the years, but the publication remained the same. Almost 40 years later, in August 2010, the City’s landmark trees were revisited. Several did not survive the test of time and some suffered from urbanization. However, the majority of the orig- inal sixty still exists today and continues to tower above Fremont’s changed landscape.

GROSE1 and R. G. OLMSTEAD Department of Biology, University of Washington, Box 355325, Seattle, Washington 98195 U.S.A. 1Author for correspondence ([email protected]) Communicating Editor: James F. Smith ABSTRACT. Recent molecular studies have shown Tabebuia to be polyphyletic, thus necessitating taxonomic revision. These revisions are made here by resurrecting two genera to contain segregate clades of Tabebuia. Roseodendron Miranda consists of the two species with spathaceous calices of similar texture to the corolla. Handroanthus Mattos comprises the principally yellow flowered species with an indumentum of hairs covering the leaves and calyx. The species of Handroanthus are also characterized by having extremely dense wood containing copious quantities of lapachol. Tabebuia is restricted to those species with white to red or rarely yellow flowers and having an indumentum of stalked or sessile lepidote scales. The following new combinations are published: Handroanthus arianeae (A. H. Gentry) S. Grose, H. billbergii (Bur. & K. Schum). S. Grose subsp. billbergii, H. billbergii subsp. ampla (A. H. Gentry) S.
